Dead cylinder on new engine ( what in the he// happened? )

what box (in your wiring harness) do you have, because if your car was originally a slant 6 itll fire only on 6, i made this mistake, check the brain for say make sure its a 8 cylinder 1!! somebody will get you the right answer here, these guys on this board are sharp as hell!!!!

Um, sorry.
Ignition boxes can't count.
They fire when the box is triggered, that's it.
